We recently had a customer ask, would their 20-year-old pump motor work on a Variable Frequency Drive (VFD), and would a VFD manufacture guarantee that the VFD would not damage the motor. This can be a tricky conversation to have and too often people move forward without giving it the due diligence that it deserves.…

Consider the following basic objectives when defining an intelligent motor relay: Increase reliability, improve safety, and reduce the operating costs of motor systems. Minimize time to commission and maintain. Standardize real time motor and operational data for integration into control system for process optimization. Access and integrate all available operational and diagnostic data for immediate…

There are some basic processes that will enhance electric motor reliability. Let’s review some of the high-level items that will give you a great start: Ensure motor design meets application requirements. What are the power demands of the driven load? What will typical operation look like for this application? Will the motor be operated on…
